Digital Seven-Hole Probe System


High-precision, integrated digital seven-hole probe system for directional velocity measurement.

Ideal for use in wind-tunnel and motorsport applications, this probe offers industry-leading functionality at a fraction of the cost.

This system provides three components of velocity, together with absolute static pressure, local fluid temperature and humidity (for density corrections) and an IMU for automatic alignment and vibration warning.

    Probes do not usually require individual calibration; the nominal (product average) calibration curve is supplied. Unit-to-unit variability results in uncertainty of about 1° at low incidence if correctly aligned. Individual calibration is available where alignment or uncertainty is critical.
